 Ramses 🇵🇸 | https://git.lix.systems/lix-project/lix/issues/1109 | 14:15:38 |
 raitobezarius | we can't reproduce on our side | 14:28:04 |
| raitobezarius | any details? | 14:28:05 |
| raitobezarius | perhaps the coredump file of the SIGABRT builder | 14:28:31 |
| Ramses 🇵🇸 | How would I get a hold of that? | 14:30:01 |
| raitobezarius | does coredumpctl offers you one? | 14:30:10 |
| Ramses 🇵🇸 | Nope... | 14:30:17 |
| Ramses 🇵🇸 | Ah wait | 14:30:44 |
| raitobezarius | if it's reproducible, you could try to hook gdb on the right process (probably the subdaemon) and follow children, but this is not super convenient to do | 14:30:44 |
| Ramses 🇵🇸 | It's sorted the other way around, I think it does | 14:30:53 |
| raitobezarius | nice | 14:30:58 |
| Ramses 🇵🇸 | Message: Process 494722 (builtin-builder) of user 872415232 terminated abnormally without generating a coredump.
Coredump entry has no core attached (neither internally in the journal nor externally on disk).
| 14:32:27 |
| raitobezarius | yeah SIGABRT alas | 14:32:34 |
| raitobezarius | but you did abort in the builtin-builder | 14:32:38 |
| raitobezarius | ok | 14:32:40 |
| Ramses 🇵🇸 | Anything else that I could provide? gdb might also not be so easy because the process crashes immediately | 14:33:26 |
| raitobezarius | pennae wrote in the issue | 14:33:57 |
| raitobezarius | the next step is strace | 14:34:00 |
| raitobezarius | do it with direct store access probably | 14:34:06 |
| raitobezarius | so something like | 14:34:07 |
| raitobezarius | NIX_REMOTE=local sudo nix-build ... | 14:34:13 |
| raitobezarius | * NIX_REMOTE=local sudo strace ... nix-build ... | 14:34:17 |
| raitobezarius | * NIX_REMOTE=local sudo -E strace ... nix-build ... | 14:34:19 |
| Ramses 🇵🇸 | Ok, trying that, I shared the --debug output in the issue | 14:36:45 |
| Ramses 🇵🇸 | strace output also in issue | 14:39:33 |
| Ramses 🇵🇸 | Ah wait, wrong strace, because of nix build instead of nix-build, one sec | 14:41:31 |
| Ramses 🇵🇸 | Updated, with the correct command now | 14:45:27 |
| raitobezarius | ok thanks | 14:49:22 |
| raitobezarius | pennae are looking | 14:49:30 |
| raitobezarius | i'm going into a meeting for now | 14:49:35 |
